Basic Safety Checks
Background
The GPT-9500 tester is a high voltage device
and as such, daily safety checks should be
made to ensure safe operation.
1. Ensure all test leads are not broken and are free
from defects such as cracks or splitting.
2. Ensure the tester is always connected to an
earth ground.
3. Test the tester operation with a low
voltage/current output:
Ensure the tester generates a FAIL judgment
when the HIGH VOLTAGE and RETURN
terminals are shorted (using the lowest
voltage/current as the testing parameters).
WARNING
Do not use high voltages/currents when the HIGH
VOLTAGE and RETURN terminals are shorted. It
may result in damage to the instrument.
